Quick Reference

The state of being alive. Pulp vitality may be tested by a thermal or electrical stimulus ( vitality test), a positive response by the patient indicating possible vitality. A thermal stimulus may be either extreme cold, such as by the application of ethyl chloride to the surface of the tooth crown, or heat from hot gutta-percha. An electrical stimulus can be provided by one of the many commercially available electrical pulp testers which are generally considered to be more accurate than thermal testing.
